Answer:

x=3

Step-by-step explanation:

1. Add the numbers on both sides of the equation to get 9 (7+2) and 12 (9+3).

9+x=12

2. Subtract the 9 from 12 to get the x by itself.

x=3

and you get your answer.

If X = 16 feet and Y = 8 feet, what is the area of the figure above ? Use 3.14 for pi .
Setler [38]

Answer:

A

Step-by-step explanation:

You can probably figure out the rectangle of 16 by 8 so no explaining there. 16×8=128. You know that diameter of the cirkel is equal to y so 8. The diameter of a cirkel is two times its radius. so 8=2r. r=4. The area of a cirkel is calculated by the formula \pi×r^2. Fill in r=4 in \pi×r^2 gives us \pi×4^2=16\pi. You only have half of the cirkel so 16\pi/2=8\pi. 128+8\pi=153.12 which is A.
